Title: Improvements in and relating to tape recording or replaying devices
Inventor: DAVIES HENRY
IPC: G11B15/66
Filed: 1965-10-15
Abstract: 1,125,616. Feeding record tapes. BRITISH BROADCASTING CORP. 29 July, 1966 [15 Oct., 1965], No. 43863/65. Heading G5R. A lacing member 21 engages the free end 18 of a tape 16 on a spool 10 and carries it past a head 34 and a capstan 36 to a location near the mouth 38 of a random store 39 which then receives tape drawn from the spool 10 by the capstan 36 while the tape end 18 remains in engagement with the lacing member 21. As shown, insertion of a cassette 11 containing the tape spool 10 causes compression of an ejector spring 42 and tilting of the lacing member 21 which is thereby released from a latch 28, allowing a second latch 31 to enter a recess 33 in the cassette 11. A hole 19 in tape leader 18 engages a projection 20 on the lacing member 21, which may then be moved either automatically or manually by means of a lever 23 to transport the tape leader between capstan 36 and pinch roller 37 to the mouth 38 of store 39, being guided by the engagement of cam follower 25 with cam surface 26. When, either manually or by means of solenoid 47, pinch roller 37 is brought into engagement with the rotating capstan 36, tape is drawn from the cassette 11 and falls into the random store 39. Disengagement of the tape drive permits the tape to be pulled back from the store 39 into the cassette 11 by means of reverse torque applied through dogs 12 and 13, but the tape leader 18 remains attached to projection 20 on lacing member 21 so that the tape is ready for immediate re-running from its starting point. On return of lacing member 21 to its initial position, the cassette is ejected by spring 42. The tape drive and an indicator lamp may be controlled by means of photo-electric sensing through transparent portions of the tape.

Abstract: 1,183,499. Preparing microscope specimens. BAXTER LABORATORIES Inc. Oct. 31, 1967 [Dec. 5, 1966], No. 49309/67. Heading G2J. A reagent for staining biological specimens, such as blood, for microscopic examination, comprises:- (a) a polychrome methylene blue solution such that when diluted with water to a concentration of one part of polychrome methylene blue solution in 2, 000 parts of total solution the ratio of the spectrophotometrically determined optical density in a 1 centimetre cell at a wavelength of 660 mÁto that at a wavelength of 620 mÁ is between 0À8 and 1À5, and (b) an eosin solution such that when diluted in water to a concentration of one part of eosin solution in 100 parts of total solution the spectrophotometrically determined optical density in a 1 centimetre cell at a wavelength of 520mÁ is between 0À3 and 0À7. In an example, the polychrome methylene blue solution is prepared by heating a solution of 1% methylene blue and 0À25% sodium carbonate to 95‹C. for four hours, filtering, ageing and adjusting the pH to 6À85 using sulphuric acid, and diluting the 1% methylene blue to 0À8% with potassium phosphate buffer having a pH of 6À9. The eosin solution is prepared by adding equal amounts of eosin Y and eosin B to a solution of Na 2  HPO 4  and Na H 2  PO 4  to provide a 0À05% solution of eosin, storing, adding 0À1% sodium azide to prevent bacterial growth and filtering. To stain a biological specimen it is immersed on a microscope slide in the polychrome methylene blue solution for 10-20 seconds, thoroughly rinsed, immersed for 10-20 seconds in the eosin solution, rinsed again and then dried in air.

Abstract: 1,047,890. Soldering. NU LINE INDUSTRIES Inc. Nov. 12, 1963 [Nov. 13, 1962], No. 44692/63. Heading B3R. [Also in Division H2] An electrical contact 34 is mounted in a glass panel 12 by means of an intermediate tube 11. As described, the contact has an annular groove 36 which is initially filled with solder 38 to the inner diameter of the tube 11, Fig. 5 (not shown). The tube 11, which may be an iron nickel alloy, is then sealed in the glass wall 12 in known manner, and the outside of the tube may be plated with gold or silver. A flux solution is then applied to the inside of the tube and to the outside of the solder on the contact and the contact is inserted into the tube from the left-hand end. The end portion 33 of the contact forms an interference fit with the end of the tube 11, and so forms an initial seal between the two parts. The whole assembly is then immersed in an oil or other non-oxidizing media which will provide an even heat to cause the solder 38 to flow into the spaces between the portion 34 of the contact and the tube 11, by capillary action. A crimped ring 20 on the tube 11 prevents the solder from flowing to the forward portion of the contact 34.

Mechanism for laying in weft or filling yarns 56 into a warp knitted fabric as it is produced on a straight warp machine comprises two conveyor chains 97, 98 between which the weft yarns - extend and which feed them towards the needles of the machine and position them in turn at the backs of the needles prior to the warp yarns 25 being fed to and lapping the needles. The conveyor chains are of unequal length and each has a series of clamps 101 which are manipulated such that yarn guiding arms 78 mounted on a third conveyor chain 69 first feed the yarn to be clamped by the clamps on the conveyor chain 98 and then move to extend the yarn from that chain until it is engaged by the corresponding clamps on the second chain 97, whereafter the yarn is severed by a cutter 135. To hold the yarn ends out so. that they are caught by the clamps on the chain 98 a tube 130 creates a suction to cause the ends to extend outwardly into the path of the clamps which engage the yarns as they pass.

Abstract: 1,057,857. Coiling. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). Nov. 15, 1963 [Nov. 16, 1962], No. 45164/63. Heading B3E. [Also in Division G6] Apparatus for winding metal strip around a core, e.g. a stack of nuclear fuel pellets, comprises (Fig. 12, not shown) two parallel rollers (33, 34), one of which is a driving roller, disposed at a spacing such that the pellets (35) rest in the roll nip. A top roller (36) is fitted to an articulated device (37) and maintains the pellets in the nip by means of springs (38). The pellets (35), which are rotated by the roller system, have an axial thrust applied to them through the agency of retractable live-centre devices (39, 40). Reels (44, 45) of strip material are mounted on a carriage (42) driven by a leadscrew and nut device (43) along a bed (41) whose axis is parallel with the rollers. After a strip (46) from one of the reels has been placed on the first pellet, the pellets are helically covered by the rotation of the rollers (34, 36) and the displacement of the carriage (42), movement-transmitting means being provided between the driving roller and the device (43). In another apparatus (Fig. 13, not shown), an expanding mandrel (46) is disposed along the axis of a rotating face plate (47) which has strip reels (48) mounted on it. The mandrel (46) and the face plate (47), which are mechanically interconnected by means of a movementtransmitting means leading to a helical motion of the face place (47) enabling the latter to advance one step along the mandrel (46) at each revolution, enable the mandrel to be wrapped with one or more layers of strips. A V-guide (49) disposed on an extension of the mandrel axis bears a row or stack of pellets (50), one end of which is forced against the exposed surface of the mandrel (46) by a pneumatic piston (51) operative on the other end of the row. The pellets, which are axially centred in the V-guide (49), are kept stationary therein by a knife (52)..After the mandrel has been wrapped, it is contracted and moved ; by the piston (51) which simultaneously introduces the pellets into the wrapping of strip material.

A nut 10 mounted on a screw 23 is rotatably mounted in a housing 3 and is provided with an external gear 22 meashing with an input shaft gear 21 connected to the flexible shaft. The input shaft is journalled in the element 26 which surrounds and is rotatable relative to the nut. A toothed portion 27 of the element 26 engages part of the slide 28. Screw 23 carries piston 35 and is fixed against rotation so that it moves axially to effect steering motion on rotation of the nut. Power assistance is achieved when rotation of the nut is resisted by the wheels and the input shaft gear starts to rotate, along with element 26, about the nut. This results in movement of the slide 28 from its neutral position to connect the valve supply part 45 to either supply line 47 or 48 through passage 55 or 53.
